INVENTOR of the easing and showing the let groove in the web, the view being taken from the explosion side ot' the casing."

Fig. 10 is a view similarl to Fig'. t) taken from the compressingV side showing the elongated groove in the web that` registers with the cross port.

Fig. 1I is a detail cross section on the line 11-11 ot' Fig. tl;

Fig. 12 is a detail vertical elevation of showing the steam engine, blower.' or a rotary air compressor.

Fig. 13 is an e larged detail perspective view of one of the pendulum devices, showing the threaded adjustment between the pendulum rod and the pendulum disk.

In the drawings, in which like nume `als and letters of reference indicate like. pa rtsin. all of the figures, 1 represents the casing` which is provided with a partition wall 2 that separates the casing into two chambers having annular peripheral walls and elosed by heads l that are secured to the flanges 3 of the. casing. The heads l of the casing' are provided with shaft hearings 5 which are located eceentrically to the center of curvature of the casing peripheral wall and in which the operating shaft t5 is journaled.

Keyed or otherwise secured to the shaft (i are two rotators Tkl', one rotator T. being located in the working chamber ot' the caring and the other T being1 located in the compressing' chamber of the easing. As the construction of each rotator is the same (eX- cept that the rotator 7a is provided with a compressed charge transterriincr duct hereinafter referred to) a detailed description ot' one of the rotators will` it is believed. sutlice. The rotator T is provided with radial ways 8`9 in which the slidingr abutments operate. there being two sliding ahutinents radiall)Y opposed on each rotator l and each sliding: abutment consists of a head 1-1 and arms 15 which are secured to the head by counter sunk screws 1G. or other suitable fastening devices. The arms 15 are slotted as at 1T to pass over the shaft (3 and at their inner ends are provided with circular t'aces 18 that merge with the adjacent faces ot' the wedge members 19 to cooperate with the pen dulum disks l1 thatare carried by the pendulum rods 42 which are fulcrmned at their outer ends on )ins -13 and lie in recesses 10 in the rotator. he rotator is counter-sunk at 11 so that cover plates 12 may be fastened by screws 13, or otherwise, over the recesses 10 to form a smooth surface of the rotator.

Each abutment head 11 is provided with a transverse socket 20 to receive the cylinv drical shank 21 of the abutment piston 22 which is rockable `in the recess 20 and is designed to engage the peripheral wall of the casing at all times section and a modification of the invention same as adapted for use as a a rotarv pump, a rotary power new charge in- -cnly with the eros-s is the exhaust port. on the working side ol the casing' and which registers with the exhaust duct 2H'.

'lhe casing ma)V he provided with a recess 2:3 at the place. ol' contact with the rotator in which a packing; plate 2U is located7 the 'contaqting .surface between the plate QU and the rotator i beine' in engagement throughout the area ot the plate 2U, except that the entrant corner 2G ma)y be rounded oli' to provide easy passage of the pistons 22. A spring 27 nurv bring,r the plate. 2o in engage ment with the rotator and a plug 28 may be provided to permit access to the spring 2T.

29 the spark plug' aperture on the working side ot' the easing to receive the spark plug 30 and that portion ot' the workin, 1,r side of the -asing in which theexplosion occurs and in which the greatest heat is generated ma.;7 be watcr-jacketed, as at 31, for cooling purposes.

The compression rotator Tti with a port 3T through which the com pressed charge is admitted to the duct 73H, the latter duet communieating with the cross outlet. 36 that registers with the groove 35 in one tace ot' the partition 2. 'the groove 35 being' a blind groove and communicating port 32 that delivers the compressed charge into the groove 533 on the working side of the partition, the `groove 33 having a perii'iheral outlet 3l to deliver the impressed charge into the workingr chamber where it is exploded at the proper time hy the spark a t the plug 30.

Si) is the new charge inlet port that communicates with the intake duct `1t), the latter duct being., adapted t'or connection with the usual carburetor.

ll'hen the invention is to be used as a steam engine. blower, pump, cte., only one, section of the casing and one rotator is re quired (see Fig'. 12) and in that form l0" desigimtes the 'inlet and 2l the outlet through which the Huid is admitted and let out.

In order to lake up wear. the disks 41 of the pendulums ma)Y he threaded onto the stems 42 as at Lll (see Fig. 13) and l deslre it understood that suitable packing' rings may he provided and located wherever found desirable. lo prevent undue escaiie of llluid, and t'iuthermore any suitable lubricating system mayv he employed in connection with in v invention.

It will be observed that by my construction the necessary differential movements of the abutments are allowed for through the action of the pendulum devices and troni the foregoing description taken in eonnection with the accompanying drawings, it is thought the complete construction, operation is provided andedvantages of my invention will be readilyK understood by those skilled in the art.
